The Funding Hub is 501 Labs' funding database: federal grants, federal assistance programs, private foundations, and community foundations, collected into one searchable place. It powers Seek's matching — free, because we're a nonprofit too.
Most sources refresh nightly; foundation filings update as the IRS releases them. No paywall, no per-seat pricing — built from public sources, free to search.
Seek matches the Hub against your organization's mission — not just keywords — and ranks what comes back: grant opportunities you can add straight to your pipeline, plus the foundations, federal programs, and community foundations most likely to fund work like yours. One profile, four kinds of funding.
The Hub is also a service: a REST API for verified nonprofits and an MCP connector so assistants like Claude can search it directly. Get a key and connect your assistant from your free 501 Labs account — sign up, then Seek → API & MCP.
